Review request for Ambari, Dmytro Sen, Sumit Mohanty, and Sid Wagle.
Bugs: AMBARI-18154
https://issues.apache.org/jira/browse/AMBARI-18154
Repository: ambari
Description
-------
PROBLEM
Under Ambari Dashboard -> Cluster metrics. It has been noticed that the metrics
Nodes_avg and CPUs_avg are showing the same data.
BUG
They are requesting the same metric (cpu_num) from AMS.
FIX
Track live_hosts metric in AMS - Number of hosts sending metrics to AMS in the
last 2 minutes. Change dashboard widget to show the new metric.
